The IS on my Canon 300mm F/4 L has stopped working. Has anyone had any experience getting the IS repaired / replaced at Canon and a ball park cost for the repair?
If you call Canon, they will probably tell you to send in the lens and only THEN will they give you a quote and you can decide whether or not to have them do the repair. Worth a try. Might turn out to be something minor.
I had the IS fail in a 24-105 lens and also in a 70-200 lens.
The 24-105 was still repairable by Canon and I had a 20% off as a CPS member so it was about $266. They replaced a lot of parts so it took almost a week.
The 70-200 was not repairable by Canon so I sent it to Michigan for $350 and waited about 7 weeks for the repair.
Hope this helps.
That's how CPS handled a repair on my 5D Mk III but it was an intermittent problem that they could not replicate. At least they refunded my money for the estimate. Thanks.
As amazing as this may sound, I think the IS has failed on both my 300MM F/4 and my 100-400MM Version 1 lens. I've tried cleaning the contacts and have tried them on different bodies, so I don't think it's the body. It struck me as a bit odd that the IS on two L series lenses would fail at virtually the same time.
What is the place in Michigan you sent your lens to?
IS on my 300f4 broke twice. NOW I read on the LensRental blog that you are supposed to turn off IS before shutting off the camera. Cost about $200-$250 for repair. Mediocre IS on that lens but really good optics.
I have come to expect multiple problems to show up together or sufficiently close together that the second one occurs before the first one is fixed. The resulting inconsistency of test results makes diagnosis so much more frustrating until you realize there may be two or even three things happening, and test accordingly.
You can't even just switch off the IS and reliably use the lens without IS, because if the defective IS does not always centralize the IS lens group then you'll end up with focus skewed one way or another so that the focus plane is not parallel to the sensor plane. I've had that happen. It means you pretty much have no choice but to get the lens fixed or get a replacement.
I do love the optics on my 300mm. Good point about using the lens without IS. Guess I'll just have to dig out my tripod and do some testing. It is curious how multiple issues can seem to crop up at the same or almost the same time. Also prevents me from selling until I get repairs and a clean bill of health.

I never turn off IS or the camera when changing lenses. I have numerous lenses without any issues, including a couple of the 300/4 IS.
My 70-200 2.8 IS II had the IS mechanism eat it and start making grinding sounds 5 years ago. I had CPS gold at the time and remember being surprised that it cost less than $500 for the repair. Not sure of the exact amount anymore, but it seemed reasonable compared to the price of the lens for the repair of a very complex mechanism.
My 85L broke briefly 2 years ago and that was going to cost $1400 to REPAIR. That was ridiculous.
